This looks like a perfecly valid test result, the test is skipped
because the controller is bound to V1 hierarchy. Nothing to worry about.

Here as well, the feature is not available hence it's not tested.

This is a bug either in the kernel or in the test, you have to figure
out what created the directory '0' before this test. My guess is that
one of tests that did exit with TCONF haven't cleaned up properly. So I
would run the cgroup tests one by one by hand and watch the
'/sys/fs/cgroup/cpu,cpuacct/' directory to see which test fails to
remove the '0' directory. Once we have the test pinned out we can debug
it further.
